Stackhouse Walmsley cistern

The Puget Sound Chapter of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) awarded the 2015 Technology award to Stack House Apartments. The building is currently operating at an EUI of 19.6 kbtu/sf/yr; making this the most efficient large multi-family building in WA state using half the energy of a typical building.   Ecotope provided mechanical and plumbing engineering services and energy efficiency modeling and consulting services.   See the full project write up and photos here.
